HOLDER AND WARMER FOR LIQUID CONTAINERS Samuel J. Mustain, Newark, N. J.Application August 15, 1944, Serial No. 549,614

The object of the invention is todevise a holder of material that is apoo-r heat conductor, such 3 Claims. (Cl. 12624.6)

as of plastic, from which the holder can be mold- I ed, and a metallicliner for the plastic material that is an excellent heat conductor, intowhich liner the tumbler or bottle fits removably and seats on a disc inthe bottom of the liner that also is a good heat conductor. Anotherobject of the invention is to devise the liner so that it willautomatically accommodate tumblers or bottles of different diameters.

Th invention is capable of embodiment in a number of differentmanifestations, but that one which to the best of my present knowledgeis the most desirable, is shown in the accompanying drawings, in whichFigure 1 is a partial vertical sectional view with parts broken away.

Figure 2 is a top view or plan of same.

Figure 3 is a perspective view of a metallic liner which rests within aholder or outer casmg.

Figure 4 is a top view or plan of the metallic liner, with part partlybroken away.

Figure 5 is an enlarged detail view, and

Figure 6 is a detailed view, in perspective, of a heating or coolingunit or disc adapted to rest within the metallic liner at the lower edgethereof and upon protuberances formed upon the inside bottom of theholder.

In the drawings, IE3 designates a holder or casing made of a substancehaving a poor heat conducting quality, preferably plastic or othernon-metallic substance, and formed with an annular projecting base I land a bottom portion l2 upon which there are formed protuberances orspacer buttons l3.

Resting within said holder is a metallic heat conducting liner or jacketM, which, in order to accommodate beverage containers of differentdiameters, is split at it to form an overlapping sliding edge. The upperedge of said liner is formed with an annular flange or edge I6 under andagainst which there is provided a scaling and spacing ring ll, of corkor other resilient material. The metallic liner is preferably bottomlessand rests within the holder upon the base portion l2, and by means ofthe sealing ring I! is spaced from the side of the holder to form an airspace 18 which functions as an insulating means between the holder andthe metallic jacket or liner.

A disc IQ of suitable heat conducting material such as aluminum, isseated within the holder and rests at the bottom thereof upon theprotuberances l3, thus providing an insulating air space 29 between thebottom of the disc l9 and the bottom portion I2 of the holder. The discis formed with a depressed portion 2| having a. cross-bar 22 whichprovides a grabbing means:

for lifting the disc out of the holder.

A beverage or edible substance such as ice cream or a salad, may becontained in a glass; vessel 23 or similar container such as a bottlewhile the container is held within the holder and rests upon the discl9.

The disc l9 may be heated, or chilled, according to desire and thereuponplaced in position within'the holder where its heat or cold will beconducted through the bottom of the liquid container and through themetallic liner as well as through the sides of the liquid container toprolong retention of either the hot or cold temperature, as the case maybe, of the liquid in the container.

While the illustrations and description show and set forth a deviceespecially designed to hold an ordinary glass, containing liquid, itwill be obvious that without departing from the principle of theinvention the shape of the holder may be so modified that containersother than a glass may be held therein, as for instance, beveragebottles, babies nursing bottles, bowls for holding foods, etc.

It is'not intended, therefore, to limit this invention to the particularform shown and described, but to include within the scope of thisinvention as defined by the claims hereof, other forms for both liquidsand solids.

I claim:

1. A liquid holder comprising a cup-shaped holder interiorly taperedinwardly from top to bottom, a liquid-holding vessel similarly ta,-pered and adapted to be seated in the holder, a heat-conducting elementbetween the vessel and the bottom of the holder, an expansible openendedliner similarly tapered having a discontinuous laterally extendingflange at its upper end and disposed between the holder and the vesselwhile surrounding and frictionally engaging both vessel andheat-conducting element in heat-exchange contact, and a resilient ringextending in air-sealing relationship between the inside of the holderand both the flange and the outer wall of the liner.

2. A liquid holder according to claim 1 wherein the liner is ofheat-conducting material.

3. A liquid holder comprising a cup-shaped holder interiorly taperedinwardly from top to bottom, a liquid-holding vessel adapted to be:

seated in the holder, 9. heat-conducting element between the vessel andthe bottom of the holder, at heat-conducting cylindrical liner disposedbetween the holder and the vessel while surrounds ing and frictionallyengaging both vessel and heat-conducting element while the latter isdirect heat-exchange relationship with the bottom of the vessel and inindirect heqt-egghange relationship with the side of the vessel throughthe medium of the liner, and resilient means tor 10 sealing the liner inplace in the holder.
